On identifiability of MAP processes [PDF]
, 2008 Two types of transitions can be found in the Markovian Arrival process or MAP: with and without arrivals. In transient transitions the chain jumps from one state to another with no arrival; in effective transitions, a single arrival occurs.

Integrative Zoology, EarlyView.Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation between breeding site type and weapon evolution. Also, gains and losses of weapons occurred more frequently in exposed‐breeding sites, an unexpected finding.

Local Search and the Evolution of World Models
Topics in Cognitive Science, EarlyView., 2023 Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

In this paper we discuss the calibration issues of models built on mean-reverting processes combined with Markov switching. Due to the unobservable switching mechanism, estimation of Markov regime-switching (MRS) models requires inferring not only the ...

Chinese Loans and Africa's Agricultural Investment: A Bayesian Multilevel Modelling Analysis
Global Policy, EarlyView.ABSTRACT Chinese lending to Africa expanded substantially after 2000, with agriculture often presented as a strategic sector in China–Africa development cooperation. This study examined whether Chinese loans to African agriculture reflected a differentiated financing strategy or formed part of a broader development finance portfolio.

An Introduction to Predictive Processing Models of Perception and Decision‐Making
Topics in Cognitive Science, EarlyView., 2023 Abstract The predictive processing framework includes a broad set of ideas, which might be articulated and developed in a variety of ways, concerning how the brain may leverage predictive models when implementing perception, cognition, decision‐making, and motor control.

A Framework for Mixed Estimation of Hidden Markov Models
, 2007 In this paper, we present a framework for a mixed estimation scheme for hidden Markov models (HMM). A robust estimation scheme is first presented using the minimax method that minimizes a worst case cost for HMMs with bounded uncertainties.

ForestForTrees: An R package to infer forest structure from remote sensing data
Methods in Ecology and Evolution, EarlyView.Abstract Estimating forest size‐abundance distributions is essential for understanding demographic processes and structural dynamics. Remote sensing provides broad coverage but often misses smaller trees hidden beneath the canopy, complicating inference of the full size distribution.

Methods in Ecology and Evolution, EarlyView.Abstract Recent advances in biologging have led to the widespread use of accelerometers, which generate high‐resolution movement data essential for understanding animal behaviour. Derived from tri‐axial accelerometry, Overall Dynamic Body Acceleration (ODBA) serves as a proxy for energy expenditure that is less invasive and more cost‐effective than ...

Animal Conservation, EarlyView.In an urban‐adjacent forested area, we investigated the spatial and temporal distribution of the wild mammal community in relation to day‐to‐day fluctuations of human presence occurring between working days and weekends. We deployed 52 camera‐traps systematically within an EU Natura 2000 area located within the metropolitan area of Florence, central ...
